Ground Shaker
Concert-Style Bass, Perfectly Engineered

Transform every drive into a live audio experience with 3.35 ft³ of deep, punchy bass that commands attention. Designed with an 11 1/8" cutout and 16" mounting depth, it easily accommodates most high-performance 12" subwoofers for maximum versatility. Its trunk-friendly dimensions of 13 1/2” H x 33 1/4” L x 17 1/2” D make installation simple while optimizing low-end output, delivering clean, powerful bass that American car audio enthusiasts crave.

Engineered from 3/4" high-quality MDF, this enclosure delivers superior rigidity and minimal vibration for consistent, powerful bass performance. Precision-sealed with Titebond silicone and glued for an airtight fit, it locks in every note for crisp, clean lows that hit hard. Wrapped in durable trunk-liner carpet, it resists scratches, spills, and everyday wear, giving American drivers a sleek, long-lasting enclosure that performs as tough as it looks.
